The primary purpose of these categories is to facilitate manual or automated checking of text in other languages.

This category should only be added with the {{Lang}} family of templates, never explicitly.

For example: {{Lang|ti|text in Tigrinya language here}}, which wraps the text with <span lang="ti">. Also available is {{Lang-ti|text in Tigrinya language here}} which displays as Tigrinya: text in Tigrinya language here.
